There are times when when we are forced to use proxy and we know , with proxy many sites are blocked, But here is a way to bypass all the Web filters. When a site is blocked , you can use this method to bypass the block!
Lets pretend for a moment that the Internet is made up of 26 websites, A-Z. The web filter blocks your browser from accessing sites X-Z, but not sites A-W. Simply make the browser think you’re going to A-W. There are a variety of ways to do this:
Proxy Servers:
This is a list of HTTP proxies. These sites may not be up forever, so you may need to search for "free HTTP proxy" or "public proxy servers" or other similar terms.
Proxy server lists:
1.http://www.aliveproxy.com
2.http://www.multiproxy.org
3.http://www.publicproxyservers.com/index.html
4.http://www.tehbox.com/proxy
5.http://www.proxz.com
6.http://www.proxy4free.com/index.html
7.http://free-proxies.com
Now that you have a list of proxies, you would open IE (internet explorer) and click on Tools > Internet Options > Connections > LAN Settings > Advanced. Enter the address and port of one of the servers from the list in the proper area (http) and make sure the "use a proxy server for your LAN" option is selected. Remember to replace the proxy and port at your terminal to the original when you're done.
Note: Some proxies listed may not work, and this method may decrease your surfing speed. By trying various entries, you’ll find one that works, or works faster.
The infamous translation trick:
Go to a web page translation site and use their services to "translate a page to English" thus accessing the blocked page through their trusted site.
You’ll notice that several translation sites are blocked, but by using less popular ones, this method can still be effective. Here is a list of some translation services. Again, these sites may not be up forever, so you may need to search for them.
1.http://babelfish.altavista.com
2.http://world.altavista.com
3.http://translation.langenberg.com
4.http://freetranslation.com/web.thm
URL Scripting:
URL scripting is the easiest method. It works on a select few web filters and is based on the same principal as the translation trick. By typing and address like www.yahoo.com@www.restricted_site.com the filter will not go into effect as it recognizes the trusted site (in this case yahoo.com)
Other tricks:
Simply open the command prompt and type:
Ping restricted.com ? restricted.com obviously being the restricted site
At this point you can take down the IP address (ex. 216.109.124.73) and enter it into the browser. If access to the command prompt is also restricted, see "How to bypass restrictions to get to thecommand prompt." If this article has been taken from information leak, then know that it involves anything from opening the browser, selecting view > source, then saving it as X.bat and opening it to opening a folder or browser and typing in the location of cmd.exe depending on the OS. I will not go into further, as this a completely different topic.
Use https://restrictedsite.com as referring to it as a secured site may confuse the filter.
Note: These are ancient methods that many new filters defend against, but still may be applicable in your situation. If not, a little history never hurt anyone.
Web based Proxies:
Another one of the easier, yet effective methods include web based proxies. These are simple in the fact that you just enter the restricted address and surf! Some of these have some restrictions, like daily usage limits, etc but you can also use another proxy (perhaps one that sucks, like a text only) to bypass their restrictions as well. Here is a list of some:

Proxy Programs:
There are many proxy programs that allow you to surf anonymously that are more or less based on the same topics we’ve covered here. I’ve added them just to cover the topic thoroughly:

Concept
Press shift key 5 times and the sticky key dialog shows up.This works even at the logon screen. But If we replace the sethc.exe which is responsible for the sticky key dialog,with cmd.exe, and then call sethc.exe by pressing shift key 5 times at logon screen,we will get a command prompt with administrator privilages because no user has logged on. From there we can hack the administrator password,even from a guest account.
Prerequisites
Guest account with write access to system 32.
Here is how to do that -
1.Go to C:/windows/system32
2.Copy cmd.exe and paste it on desktop
3.Rename cmd.exe to sethc.exe
4.Copy the new sethc.exe to system 32,when windows asks for overwriting the file,then click yes.
5.Now Log out from your guest account and at the user select window,press shift key 5 times.
6.nstead of Sticky Key confirmation dialog,command prompt with full administrator privileges will open.
7.Now type “ NET USER ADMINISTRATOR aaa" where “aaa" can be any password you like and press enter.
8.You will see “ The Command completed successfully" and then exit the command prompt and login into administrator with your new password.
9.Congrats You have hacked admin from guest account.

Securing Vista by Setting the USB drives to Read-Only. By disabling writing on USB drives it gives an added measure of security from unwanted copying of files.
Common Security measure that is implemented Corporate Computers and or Public Computers, but basically I use this hack to annoy anyone who uses my laptop without my permission. Of Course, I had set my laptop to have multiple users and of course my own user account that has Administrator rights.. and all other have standard User accounts.
Ok, Enough with the chit-chat it’s time to work :
To Disable
Click on the Start Orb -> then Click Run to go the Run Dialog box
On the Run Dialog Box -> type Regedit
On Regedit navigate to this location :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
On the Right hand side look for the value “WriteProtect” it has a DWORD value of 0×00000000(0)
Change the DWORD value to 0×00000000(1) to disable
Exit Regedit
Reboot your Computer.
And You’re all set.
The Microsoft line of Operating Systems has been around since the beginning of the personal computer and is considered to be one of the earliest forms of user-friendly operating systems around. It allowed non-technical people and even kids to learn how to use them without being a programmer as opposed to the command line interface most older generations of pc’s had. The first inn ovations of GUI or Graphics User Interface or the use of graphics icons to signify the many parts of the computer began with the early days of Apple when Jobbs was handling all the marketing of the first prototypes as well as the first generation of the Mac.
Windows has captivated the market, though Apple still has the Mac line of desktop computers that was generally better than any PC you could buy, however high-end people stuck with cheaper PC’s that can be mixed and matched. Those were the days when floppy’s and Cd’s were king and just about anybody could install a copy of the now proprietary Windows operating system from bootleg copies all over the place. Then Microsoft began to notice that they were losing profits from these bootlegs and tried to initiate copy control programs that utterly failed to curb the problem much like the piracy seen in DVD’s and Music CD’s today.
Not so long ago, we had the infamous WGA which first tried to make it’s entry unannounced, quickly noticed and criticized by the growing mob of angry computer users who hated Microsoft for their Capitalist ways. It was deemed illegal and an invasion of privacy so the company made it known, asking permission before it made entry to subsequent installations of the Windows operating system. Then came the browser wars, and again Microsoft faced challenge from the many budding browsers that were making their way into the computing industry saying that Microsoft was engaging in anti-competitive activities, bundling their Internet Explorer that stopped other browsers from working from within the Windows platform.
Microsoft has had a long and illustrious history with the rise and fall of many of it’s products that used to grace almost all computer screens the world over. Today, you get the nagging reminder known as WGA telling you you have a bootleg copy of the OS, and that you need to purchase a legitimate copy to continue using the system without impediment. Some say it causes crashes after sometime, Microsoft says it does no such thing and merely reminds people to get legitimate copies of the operating system (who do you beleive?). Whatever people decide to do when the new and seemingly improved Windows 7 makes it’s entry is anybody’s guess. Just hope it meets all expectations and does take the throne from windows XP, still the king of the OS’s the world over.
You can check the location of all your orkut friends by using the orkut friends map feature. This feature uses google maps to let you see where all of your friends are living around the whole world. Orkut friends map combines the power of google maps with orkut profiles. You need to follow these simple steps to use this cool feature in orkut:
1. Click the view friends link in the my friends box on your right on the orkut home page.
2. Now click on the friends map tab at the top of the page.
You can now click on a friend’s profile picture to see their location on the map shown. Please know that if we don’t have map data for a particular region or if your friend chose not to put their location in their orkut profile, you’ll see a message “(not on map)” below their profile name.
Please know that if we don’t have map data for a particular region or if your friend chose not to put their location in their orkut profile, you’ll see a message “(not on map)” below their profile name. You can also click on the “tiny little blue men” to see your friends’ locations. By clicking on one of these figures, a bubble will pop open to let you know which friend lives in that location.
When you are signed in to orkut account, you can use this cool feature directly by using this link. http://www.orkut.com/Map.aspx
Most people want to be able to locate a file on a file system (hard drive), Microsoft makes this easy with the find utility in Windows.
A lot of you probably host your web sites on systems that run UNIX/Linux as an operating system. These operating systems also have a find utility, it is a command line tool.
You can get reference information on the find command by using the man(ual) pages.
i.e. man find
The easiest way to use find is from your current directory (pwd).
find . -name "______" -print
The pattern you are looking for would go where the underscores appear above.
i.e. find . -name "*.css" -print
Though a common term in the computer age today, it needn’t bring out doubt in users. We all know what a proxy is, something that’s used instead of the real thing, especially when it comes to dubious deals where you send a proxy to carry out an intended act instead of the real person. Similarly in the world of servers, proxy servers are fast gaining popularity. A closed proxy can be accessed by limited people and permits using someone else's computer to conceal your identity and/or location. An open proxy refers to a proxy server that can be accessed by anyone who uses the Internet.
By and large, a proxy server permits users in a particular network group to accumulate and further internet services such as DNS or web pages. Consequently their bandwidth usage is lessened and controlled. In case of any open proxy, however, every user on the Internet can avail of this forwarding service.
The open proxies, also known as anonymous open proxies, allow users to hide their true IP address from the service they access. In fact the use of proxies has at times been intended to abuse or disrupt a service. This obviously includes breaking its terms of service or the law. For such reasons open proxies have been viewed as problematic from time to time. They have been under severe scrutiny because school children, as well as office staff have been known to use it time and again to access restricted sites during work hours.
The use of proxies can work to your advantage as it ensures that no one can take advantage of you in this visual world. This is very true in reference to users who use social forums on a daily basis. Users may be getting onto such sites to gain knowledge, learn about latest developments or also increase their social networking base, but there are always those who are on the prowl to find the vulnerable and easy targets. And just incase you’re targeted your life could be a mess. Your credit card accounts could be tampered with, someone would know all your details and you could be stalked or blackmailed and worse still you’d find yourself visiting sites and forums which you never have. You could even be made the next porn star. For your identity to be protected and enhancement of online security, the use of proxies works just fine. This permits you to access facebook, hotmail, youtube, and others without a worry. These may be popular as fun sites, but they also promote educational needs, helping you learn along the way or even have a secure social networking group you can depend on. Along the way you can make alliances that can assist you in getting a job, help make business or even make a friend. The opportunities are endless, as long as you keep yourself safe from prowlers.
A computer can be run on an open proxy server without the owner knowing this. This is possible because of misconfiguration of proxy software used in a particular computer. Malware, viruses, trojans or worms are all used for this purpose. Open proxies are slow, as slow as 14400 baud (14.4 kbit/s), or even below 300 baud. At times they could keep alternating between fast to slow every minute. PlanetLab proxies are quicker and were deliberately put in place for public use.
Despite the popularity of proxies, because of the controversies surrounding them, there are systems in place that don’t permit their usage everywhere. IRC networks routinely test client systems for identified open proxy types. Mail servers can be configured to routinely check mail senders for proxies with the help of proxycheck software. Mail servers can also consult various DNSBL servers that block spam. Such servers also list open proxies and help in blocking them.
Nevertheless, anonymous open proxies have also been hailed because they enhance ambiguity, in other words security when browsing the web or engaging in other internet services. The use of proxies conceals any users’ true IP address. This is a boon because your IP address can be used against you. It can help miscreants construe information about any user and accordingly hack into his/her computer. Open proxies are being looked upon as the next big thing when it comes to dodge efforts at Internet censorship by governments and concerned organizations. There are various web sites that make available updated lists of open proxies on an ongoing basis.
Have you ever sat in front of your computer and wished you could show someone else what appeared on your screen?
Maybe you were experiencing a problem, or couldn't figure out how to make something work, but you knew if someone else could see what was happening on your screen, they could help you fix the problem immediately.
Ever had a phone conversation with someone about a particular business topic, but you just couldn't "connect" with your ideas because it was too hard to explain over the phone?
Now, visualize jumping on the phone with that same person and literally sharing your computer's desktop to collaborate, discuss, and create virtually anything together, even if you are separated by thousands of miles.
Though this may sound like an episode of Star Trek, remote computer sharing is actually a daily business reality.
Imagine you need to take a trip and you either don't want to or can't take your computer.
The thought of emails piling up for days makes you crazy and you also need to monitor some things on your pc.
Instead of trying to lug your laptop (or fit your desktop into your suitcase), you can use "remote desktop" software that allows you to access your computer through the Internet from any other computer in the world.
One of the most common remote desktop services is GoToMyPC.com, which provides a safe and secure way for you to go down to the local internet café, log on, and access your office or home computer just like sitting at your own desk.
Now, before you panic and think anyone can access your computer, let me explain security.
First, you log in to the GoToMyPC.com website with a username and password.
Once logged in, you then click a link to log onto your PC, which will then ask you for another password.
GoToMyPC.com has even thought of a solution for those of you worried about people looking over your shoulder as you enter your passwords on a public computer or if the computer you use might carry a keystroke logger.
Before leaving home, you can program in a series of up to 99 passwords that only work one time.
This means even if someone watches you log into your computer or records your keystrokes, the password you used won't work again.
If a would-be thief tries to access your computer too many times, GoToMyPC.com will shut down all access attempts to your PC.
The advent of wireless routers has helped small offices and home computers interconnect and function fast. No more sharing of files with thumb drives or squabbles over who will access the internet fast. If you have notebook or laptop you can keep repositioning your place of work within your house, such is the convenience of wireless networking. With a little bit of planning you can configure a network that suits your business requirements the most.
The task of settling for a particular model of wireless router can be very puzzling. There are many models from various manufacturers and each with many features. Some of the features of wireless routers to check out before buying one are explained below.
Router Functionalities
Firewall
Firewalls are ideal for home networks. They help in protecting home use computers by stalling the destructive efforts of other official websites and potential hackers. This software or hardware device filters the information coming through the internet connection, flagging the information that is not to be allowed through. You can find some such models at:
VPN Pass through
VPN pass through feature of routers allows traffic between the endpoints and does not support one of the endpoints. This feature is ideal for routers of home use or small office setups; they are less expensive than a router with full VPN that supports the endpoints.
DHCP server
Dynamic Host Configuration Protocol (DHCP) servers can be implemented for windows based system. The server automatically assigns an IP address to the computer’s TCP/IP stack software.
Wireless Access Point
The performance of your network will depend on signal strength of the wireless access point. Before you position it, find out the exact location from where it will give the maximum network range.
DSL Modem
Digital Subscriber Line modems are faster than regular modems and can use the existing phone lines. Both internet connection and phone lines for telephone calls can be used simultaneously.
Voice over IP gateway
VoIP routers have both wireless networking feature and telephone terminal adapters. With this feature the network can access both Internet and voice communications.
Protocols
These are formats for transferring data between the various devices. The protocols determine the various aspects of the data like compression types, delivery and retrieval by devices and error checking. The standard protocols differ in their various features, so in order to communicate with other computers correct protocols must be selected.
Internet Protocol (IP) enables unique addressing for computers.
When used with transport control protocol, it is referred as TCP/IP.
The newer IP version 6 is referred as IPv6. This version addresses 16 bytes in length.
DHCP: Dynamic Host Configuration Protocol assigns dynamic IP addresses to devices on a network.
Routing Protocols
The information packets have to be routed by a series of routers to get to its destination. Latest routers automatically exchange route information with other routers through the use of routing protocols.
While configuring the router on your own, you have to choose what types of routing protocol you have to install and configure.
RIP version-1: It is a dynamic protocol and automatically figures routing tables on its own, thus manual inputs are not required.
Encryption Standards
This feature configures the virtual private network, encryption hardware advanced integration modules and the network modules.
Data Encryption Standard - applies 56-bit key to 64-bit block of data. This is the most commonly used encryption standard. A single key is used which is very difficult to break.
Triple DES (3DES) - applies 3 keys in succession making it more difficult to break the code.
Advanced Encryption Standard (AES) will be the next encryption standard for commercial transactions in the private sector.
MD5
SHA 1
Modulation
There are many standards of modulation. The most commonly used types are:
QAM: Quadrature Amplitude Modulation, a dominant modulation technique for high speed digital signals.
CCK: Complimentary Code Keying is a modulation scheme to operate in data speeds up to 11Mbps in the RF band.
OFDM: Orthogonal Frequency division multiplexing modulation is used for even higher speeds of 54Mbps.
DSSS: Direct Sequence Spread Spectrum use wideband signals that are not easy to detect and resists jamming attempts.
Security
Today no home and office network is secure. To counter the hacking efforts of hackers, look for good built-in security functionalities. These will ensure that your system doesn’t slow down, those within the range of your wireless are not able to view your files, emails, instant messages, usernames and passwords. Depending on the security features you can also block spams, illegal activities with your internet connection and prevent loading of dangerous software.
This however doesn’t mean your network is completely secure.
Some steps that can be taken are:
- Enable WEP, wired equivalent privacy encryption provides security to WLANS. The WEP keys encrypt the data stream.
- Turning on WPA encryption. The Wi-Fi protected access adds on the authentication and encryption features WEP explained above.
- TKIP, Temporal Key Integrity Protocol covers up for the encryption weaknesses of WEP.
- WPA2 protection is the latest one and provides high level of protection.
- Enable wireless MAC Address filtering.
WEP Encryption length
The WEP encryption is based on a combination of secret user keys and system generated values. The key encrypts and de-encrypts the data that is transferred between the access points and the clients. There are two versions:
The earlier version supported 40-bit encryption; the key length was 40 bits and 24 additional bits of system generated data, thus a total of 64 bits.
Easy decoding of 40 bit WEP encryption encouraged vendors to go in for 128-bit encryption. 128-bit encryption has a key length of 104 bits.
Antenna Type
The omni directional antenna of routers broadcast 360degrees around the router. Position them in such a way that you can make the most of the radiating signals.
External antennas can add strength significantly, thus giving a wider range and increased network performance when compared with the performance of in-built antennas.
Detachable antennas disable 802.11a lower band communications when detached. On attaching the antenna the lower band is enabled. Thus they can be screwed into the device and can be upgraded easily.
The third type is the internal integrated antennas. These antennas are built-in, and hence cannot be changed or directed.
Brand Name
Wireless routers are still evolving, and at this infant stage it will do good to stick to one brand. Switching between brands can lead to compatibility problems. Linksys and Netgear wireless routers are among the few companies that have the highest wireless router ratings a company can get.
Linksys
Linksys wireless routers are easy to install and are reputed to give good performance and signal range. The various features that the router supports are protection from hackers with NAT technology, VPN pass through, and can encrypt all wireless transmissions. Most of its models have excellent performance and extremely useful support features. Some of the features are the firewall and routing capabilities, MAC address filtering and virtual server support. Most of the models are easy to configure with the browser-based configuration.
Netgear
Netgear wireless routers have not only superior looks but also good signal strength and wider range. Security features are good and are taken care of with WPA-PSK, WEP (128-bit). Netgear markets wide range of wireless routers for home networking as well as business networking. The selling factors are ease of use, reliability, quality and security.
Apple
Customers loyal to this brand can go in for wireless routers of this brand; they are however priced higher than models of other brands with similar features. Security and support features are good.
In your car, the firewall sits between the engine compartment and the front seat and is built to keep you from being burned by the heat of the combustion process. Your computer has a firewall, too, for much the same reason – to keep you and your data from being burned by hackers and thieves who are the unfortunate creators of “Internet combustion” and destruction.
The firewall, a “combo” approach of software that regulates and monitors hardware and communications protocols, is there to inspect network traffic and all the “packets” of information that pass through to your inner sanctum, your CPU and hard drives. A firewall will rule out the possibility of harm, or at least greatly minimize, by noting and quarantining potentially harmful “zones” and will either deny or permit access to your computer based on the current set of rules that applies at the time, depending on many (very many) factors.
Basic tasks and settings
The basic task for a firewall is to regulate of the flow of traffic between different computer networks that have different “trust levels.” The Internet is full of countless overlapping zones, some safe and some totally deadly. On the other hand, internal networks are more likely to contain a zone or zones that offer a bit more trust. Zones that are in between the two, or are hard to categorize, are sometimes referred to as “perimeter networks” or, in a bit of geek humor, Demilitarized Zones (DMZ).
Without proper configuration, a firewall can simply become another worthless tool. Standard security practices call for a "default-deny" firewall rule, meaning that the only network connections that are allowed are the ones that have been explicitly okayed, after due investigation. Unfortunately, such a setup requires detailed understanding of network applications and a great deal of time and energy to establish and administer.
Who can do what?
Many businesses and individuals lack sufficient computer and network knowledge to set up a default-deny firewall, and will therefore use a riskier but simpler "default-allow" rule, in which all traffic is permitted unless it has been specifically blocked for one of a number of possible reasons. This way of setting up a firewall makes “mysterious” and unplanned network connections possible, and the chance your system may be compromised becomes much more likely.
Firewall technology had its first growth period in the computer technology revolution of the late 1980s, when the Internet was a fairly new in terms of its global reach and connectivity options. The predecessors to today’s hardware/software hybrid firewalls were the routers used in the mid 1980s to physically separate networks from each other. However small the Internet began, it was ultimately undone by supremely fast growth and the lack of security planning, and therefore there were the inevitable breaches caused by older (“prehistoric”) firewall formats. Fortunately, computer pros learn from their errors, and the firewall technology continues improving daily.
More and more persons and companies seem to realize lately that technology is working to their advantage. This is how they’ve come to discover the numberless opportunities offered by the VoIP technology and how easy it can be to make Pc to Phone calls.
VoIP, meaning Voice over Internet Protocol, is an innovative advanced technology that allows audio data transmission by means of an internet connection. The major advantage of the VoIP technology is the possibility to lower the prices very much and maintain a high quality of the Pc to Phone calls at the same time. Thanks to these features, the VoIP technology is now being extensively used not only by large or small companies using Pc to Phone services, but also by lots of individual persons who use Voice Chat or Pc to Phone services. Depending on the VoIP provider, users might need a personal computer, a special VoIP phone or a traditional phone connected to a special adapter. Some VoIP services may only allow you to call other people using the same service, but others are less restrictive and may consent to calling just about anyone who has a phone number, including local, long distance, mobile, and international numbers.
There is no joke or dream. Indeed, anyone can make local, long distance or international Pc to Phone calls, which means that the voice conversation initiated by someone from his personal computer (PC) can be routed over the Internet or through any other IP-based network to a phone. In other words, Pc to Phone means calling a phone number from a Pc with an internet connection. The voice is converted into a digital signal that travels over the Internet. When calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. This is by far the most beneficial service, with large functionality, providing an outstanding quality at the same time.
Pc to Phone service is qualitatively superior to any other voice chat free service. More than that, when using Pc to Phone services, the person at the other end of the “wire” is not compelled to have an internet connection. A simple phone line will do; and if you don’t have a phone line in your house, then you can use a public phone booth. However, in order to generate Pc to Phone calls, you need to have a personal computer with a standard internet connection, minimally a dial-up connection. The moment the conversation is started, you must be connected to the internet.
Specialists recommend using headsets when making calls through VoIP services. The model of the headset you want to use is entirely up to your preferences or budget. USB headsets often offer higher quality than sound card headsets, but they are a little bit more expensive on the market. In all cases, do not use desktop speakers for listening to the call. Although the quality may sound fine to you, the people you call will hear a disturbing echo. All in all, the audio quality on the VoIP-based networks is equal to the quality of standard fixed telephone lines. And when minor details, such as always using headsets during conversation, are complied with, you will have the opportunity to enjoy the highest voice quality and the lowest delays in the communication field.
To cut a long story short, we must underline the fact the VoIP technology may be used in each and every location wanted by the caller. For instance, locations such as airports, parks, and café shops allow their customers to connect to the internet and make PC to Phone calls using VoIP services wirelessly.
Web Conferencing is, very simply, a meeting, conference or seminar that is held over the World Wide Web. Web conferencing can refer to audio, video or text-based conversations and are conducted in real-time.
Web conferencing is an incredibly useful resource for anyone who trades within a global market place. It literally allows you to be in two places at once - sitting at home or in your office whilst conducting a meeting with someone one the other side of the world.
In its simplest form web conferencing can take the form of free downloads such as Microsoft NetMeeting or Yahoo Messenger. Subscribers can participate in text-based 'chats', inviting others into their conversations and being able to communication in real-time. Add a simple digital camera to this equation and you have the beginnings of an elementary web conferencing application.
At the other end of the scale, the most sophisticated applications allow seminars and presentations to be made to hundreds of delegates at the same time. Meetings can be fully interactive, allowing question and answer sessions, the sharing of files and documents and slide show presentations to be broadcast.
What Can I Do With Web Conferencing?
How you choose to use web conferencing will very much depend upon your line of work. A webinar (an online seminar) is less interactive than a web meeting, but is a very effective means of presenting sales pitches, performance reviews and delivering staff training.
A web meeting on the other hand, can be fully interactive not only in terms of audio and video but also by allowing the sharing of documents and files and viewing them online.
What is Online Collaboration?
Online collaboration is an excellent resource for project management, especially when team members are located in different geographical locations. Online collaboration provides an advanced level of document management and file sharing. Documents and files can be viewed, modified and updated online and in real time.
What Are The Benefits Of Web Conferencing?
The main benefits of web conferencing are to be found in terms of time and money savings. The need for travel is greatly reduced, and therefore so are the associated costs of travel - tickets, accommodation, subsistence, to name but a few. Employees spend less time waiting for flights, travel or just generally being away from their desk and therefore have more time to spend productively.
Satellite high speed Internet is the best way to get on the information superhighway called Internet especially for people in rural and other remote areas. A broadband satellite Internet connection is an excellent option for people residing in rural areas where Digital Subscriber Line (DSL) and cable modem connections are not available or if available the condition is poor.
What is Satellite Internet?
In a satellite Internet connection the upstream (outgoing) and the downstream (incoming) data are sent and received from a computer via satellite. The signals are sent to the satellite with the help of a satellite dish antenna and a transceiver that operates in the microwave portion of the radio spectrum. As the nature of the broadband satellite Internet connection offers high speed it is considered really a good option for Web browsing and for downloading of files.
Satellite Internet providers can get a satellite Internet connection installed even in remote areas where even the most basic utilities such as electricity is lacking. In such a situation if there is a generator or battery for power supply to run a computer system you can think about getting a satellite Internet connection. Thus, getting a broadband satellite Internet connection is the best choice as location and hi-fi infrastructure is not an issue here. The dish provided by the satellite Internet providers is designed to pick up the signal from practically any where.
Pros and cons of satellite Internet connection
Before you seriously think of getting a satellite broadband Internet connection, you must be aware of the pros and cons associated with the usage of broadband satellite Internet. The biggest advantage is undoubtedly the convenience related to the use of this fast growing technology. Secondly it always promises fast and reliable connection speeds without any location barrier.
And speaking of cons the integrity of your satellite Internet connection largely depends on the weather condition. Rain, moisture, strong winds, and other obstructive weather patterns determine how well the transmitter provided by satellite Internet providers communicates with the Internet satellite service. But this problem can be resolved easily with the help of a signal amplifier or signal locator. With the help of this additional hardware connection can be made stronger and more resistant to disturbance with a signal amplifier.
Now if you need a satellite connection find a good, reputed satellite Internet service provider and place your order. But before ordering there are certain basic requirements for broadband satellite Internet connection that you need to take care of.
Apart from a clear view of the sky and a solid roof to install the satellite dish antenna, you will also need a powerful computer system to enjoy uninterrupted Internet connection anytime, anywhere. You need a Pentium II 333 MHz or faster system with Windows 98SE or Windows Me with 64MB RAM, while for Windows 2000 and Windows XP the requirement is 128MB RAM. There must also be free hard drive space of 20 MB, one extra USB port and CD-ROM drive.
Even though satellite Internet connection is bit costly as compared to other types of broadband connection, it is a good option as it comes bundled with plenty of benefits which will serve you well in the long run. Get your own broadband satellite Internet connection today as life without the Internet technology is simply impossible to visualize.
A hard disk’s performance becomes even more crucial when you are handling large amounts of data at one point in time such as work that is graphical in nature, or while working with databases. Imagine establishing your company’s database and having to wait for eternity just because your computer’s speed is slow. Not only will you lose out on your valuable business time, but it will also affect your productivity.
Therefore, the speed of the hard disk can be directly related to the speed with which you can get your work done without facing any system performance issues. A hard disk is, indeed, a technological wonder with components that are fragile and yet capable enough to give a strong boost to your system. The data is stored on circular platters and these platters are well protected so that no air or dust contamination can affect them. Each of these platters has a thin layer of magnetic film on them and data is stored in the form of binary digits i.e. 1’s and 0’s.
These binary digits represent different characters and when these characters are read back by the disk head, the data is processed and retrieved. A hard disk has user-friendly features such as a disk defragmenter that can increase the performance of your computer system. Since our data needs are ever increasing, we keep writing and deleting files regularly.
This constant activity leaves the disk in no specific order for the new files. Therefore, when you write a new file on your system, this file will get written in the gaps on the disk. Since a single file will get written on different parts of a disk, the disk will have to read different parts of the same file from different parts of the disk rather than reading it as a streamlined data. This activity is called fragmentation.
Disk fragmentation can significantly decrease the performance of your disk. Therefore, you should defragment the disk on a regular basis to ensure that the files get sorted out in a specific order and to make the disk perform faster. Hard disks can hold more than 100GB of data and portable hard disks are increasingly being used as a backup option. Hard disk manufacturers are trying to increase the capacity of a hard disk by increasing the aerial density of the hard disk. Industry experts predict that this density will increase by 40% each year. A hard disk is very delicate, comprising of various very tiny components that need to be handled very carefully.
As we have discussed earlier, a hard disk consists of circular platters. These platters are read by the read-write heads that are located above the surface of the disk on a thin air platform that is created by the speed of the platter’s rotation. This assembly has other frameworks that are equally precise and fragile. In addition, the speed with which this assembly rotates is very fast. Any disruption can cause the disk to undergo severe damage.
Therefore, if there has been some physical damage to the disk, you should never attempt to rectify the error yourself. Since a hard disk is very prone to air and dust contamination, a hard disk error can be looked into only in a clean room environment. Hard disk errors can be very critical and it would be best to have a data recovery specialist look into these errors to assess the extent of damage.
Notebook shopping can be rewarding provided you are literate about the various features that various manufacturers offer. Popularity of notebook has soared more because of its portability without any compromise on performance. Since buying a notebook can be once in few years affair you need to be clear about its use. Following is a condensed notebook buying guide dealing with just the main factors you need to keep in mind before purchasing one.
Buy by features-the core components
The need of the hour today is to carry work and information and instant access to internet to present information for sales and clinch business deals. So obviously the size and weight of the notebook you carry around matters a lot. Notebooks are categorized both on basis of weight and on basis of screen size.
Size
The four basic sizes are:
1.Tablet PCs have all the normal functions. There is the added advantage of being able to physically write and manipulate applications with a specially designed input device- the Pen. The two types are the slate and the convertible.
Example: Lenovo ThinkPad X41 2526,
Lenovo ThinkPad X41 (S5519073) PC Notebook .
2.Ultra portable notebooks are extremely light with small keyboards and screen. There is however no compromise on emailing and web surfing capabilities and can connect to cellular broad band wireless providers. The CD/DVD drives are removed to save space.
Lenovo ThinkPad X60 Ultraportable
3.Thin and light notebooks weigh five to seven pounds. The swappable media bays make it possible to switch between CD/DVD and spare battery. You will have to recharge often else carry the power adapters too.
Lenovo ThinkPad X60s (X60s_Standard_Ultralight)_BT...) PC Notebook
4.Desktop replacements are powerful notebooks, only that you won’t be able to carry it around much. Available with powerful processors, adequate memory, plenty of drive space and wireless connectivity. The negative factor associated being comparatively lesser battery life due to power draining screens and the powerful components.
Weight
This feature is crucial since the notebook is intended to be carried around. A frequent flier would prefer lighter systems with some compromise on its functionality. While a home user wouldn’t mind slightly heavier systems. The travel weight specified must include the weight of power adapters and media bays but most manufacturers mention just the weight of the system and its batteries. Check out the models in the following three ranges: 0.6 to 4 lb. Most ultra portables come in this range. 4.1 to 5.7 lb. Thin and light models with reasonably good battery life. 5.8 to 10.1 lb. Desktop replacements weigh around 7 lbs.
Display size
Notebook displays come in thin film transistor Liquid Crystal Display (LCD) models, perfectly flat and just half an inch thick, as they are easily portable. Specifications state TFT Active Matrix Display or LCD Display. If you are a frequent traveler, a good combination of small size and less weight will be easier for you to carry around. In case you wish to view movies bigger displays will well serve the purpose. Check out the three commonly available sizes.
8.9 to 11.1 inches- most of them have smart designs and good battery life, but reduced video quality limits its uses
12 to 14 inches- good for watching movies and for gaming
14.1 to 17 inches- for gorgeous display and powerful performance, so, ideal for business presentations
Display resolution
Displays have another criterion which needs scrutiny before purchase. It is the display resolution- higher the resolution cleaner and crisper will be the image. Resolution is number of pixels across the width and height of screen. 1024 x 768 means 1024 pixels across the height and 768 pixels across the width. Pixels mean the individual dots that make up the picture. In specifications the standard screen and widescreen is specified with abbreviations as XGA, SXGA, WXGA, WSXGA or WUXGA. The widescreen are fast becoming the rage because the reading space increases more with slight increase in size.
1024 x 768 Small displays 12.1 in. usually have this resolution XGA (1024 x 768), WXGA resolutions (1280 x 800). Larger screens too come with so low resolutions and they are cheap and ideal for budget computers.
1400 x 1050 Many large displays 12.1 and 15 inches come with this resolution like SXGA+ (1400 by 1050) and give very good picture quality.
1920 x 1200 Models with such resolution WUXGA (1920 x 1200) is ideal for making movies as there is more detail in the image and more work space on the display. However a negative factor associated with such high resolution is that the fonts tend to be smaller, difficult to read especially for people with poor eyesight. This factor is corrected by changing the font size in operating system but the correction can have unintended effects on other programs.
Display screens
The screen is of two types Glossy and Matte. Glossy screens have the advantage of reduced screen door effect i.e. reduced black spaces between pixels, thus improving the contrast and brightness of the image. The disadvantage is the reflective ness causing eye strain. Matte screens don’t have this feature and are a lot cheaper than glossy ones. The brightness of LCD screen can be adjusted and a lower setting can help conserve power. The brightness is adjusted by adjusting the intensity of the back light inside the panel that illuminates the screen.
Processors
This is the most important feature of notebook. There are types of processors and subtypes of processors. Sub-types being ultra low voltage, low voltage, and normal chips of say Pentium M or Intel Core Solo. Low voltage processors give good battery life. So depending on the ultimate application you intend to use the specifications will vary. Since notebooks cannot be easily upgraded (any upgrade of CPU would require dismantling the system to the core and replacement of motherboard, RAM, and may be add another heat sink.) it will be worth the money if you spend enough for fast processors to satisfy your current and future requirements. No single processor can fit all needs and functions, it may be ideal for single function but not for all tasks.
Processor brands
Two of the leading companies manufacturing processors used in notebooks are AMD and Intel. The processor market is entirely in the grip of these two companies. The clock speed of single core versions of the processors produced has touched the upper limit. These single core processors develop heating problems when multiple functions are carried out. Both Intel and AMD have developed the dual core technology in its processors that has increased the multitasking capabilities of notebook PCs. Intel uses the SpeedStep technology which senses and reduces frequency and power consumption if power is drawn from battery and increases the same if power is drawn from external source. AMD features PowerNow for the same purpose. AMD Intel Knowledge of the processor type will be handy to install the correct packages. Some processor types in notebooks are: AMD processors Intel processors are Celeron M Pentium 4 Core Duo Core 2 Duo Processor speed is another factor to be considered. The one you would use for just surfing and as a letter box would be cheaper and slower, while heavy duty multitasking, running multimedia applications require faster processor and cost more.
1.1 to 1.5 GHz- A do everything notebook processor like creating and sharing documents, net browsing, send and receive mails, write or receive text messages, make phone calls etc.
1.6 to 2.1 GHz the double core processors with this speed give good performance and long battery life.
2.2 to 3.3 GHz The dual core CPUs are the fastest. Programs run faster with such fast processors, they cost more too. Recording videos, playing extremely high definition videos, touching up digital photos, video editing all require fast processors. These fast processors consume more power especially when used in portables.
Memory
The memory requirements depend on OS and the applications you plan to put in use. RAM is used to process the program information. More is always better for faster loading, printing and down loading of your files. Buy the ones that have easy to access memory slots as you would very soon want to upgrade this feature. There are two ranges of RAM available.
128 to 256 MB- this space can manage your daily mails and normal applications
512 MB to 2048MB for improved performance A memory specification like 512 MB (DDR2 SDRAM) indicates; the space is 512 MB, DDR2 (double data rate 2 synchronous dynamic random access memory) is the memory type, latest widely used one. DDR2 is the new version of DDR. Speeds are assigned by the memory type and clock rating and another method by bandwidth.
Drives
Drives provide the storage for the computer programs. Again this choice depends on how much data you wish to store. Some laptop models come with swappable drives which increases the flexibility.
Drives have three specifications: size, type of interface and speed. Notebook hard drives come in two sizes; 1.8 inch and 2.5 inch. The 1.8 inch ones are mostly in ultra portables, while the 2.5 inch size Hard Drives are used commonly in other notebooks. IDE and Serial ATA are the two types of connectors between hard drives and computer and of the two it is IDE which is more commonly used. Speed at which the hard drive spins also determines the performance. Most notebook hard drive spins at 5400 rpm speed. A higher spin rate of 7200 rpm gives better performance but uses more power. Following is categorization based on storage space. 1 to 31GB-Mostly incorporated in low cost budget notebooks. 40 to 80GB- Home users using notebooks for photos and videos, in addition to normal surfing can opt for 80 GB hard drives. 100 to 256GB- Most multimedia notebooks have dual hard drives of 200 to 320 GB. For gaming uses 100 GB should suffice.
Battery life
The battery life definitely depends on the chores or tasks that are carried out; some of them being the applications like MS Office, Norton AntiVirus programs, Netscape. Huge amount of power is consumed for displaying images on the screen. The rest of the system like the core-logic, chip set and memory too draws power. Notebooks designed to handle large power consumption weigh more as they come with large batteries and thermal heat sinks. If you are traveling too frequently go for batteries that have longer run time or purchase two of them and use both of them equally. Prefer the notebooks equipped with lithium-ion rechargeable batteries. Check with dealer for battery settings and battery backup so that it lasts long. Normally batteries can last 700 charging cycles. Check the following three categories of battery run time: 1.5 to 3 hrs-great for viewing movies, video chats and photos at home, viable for budget desktop replacement.
3.1 to 4.3 hrs
4.4 to 12 hrs
Notebooks categorized Business Notebooks
These systems have high flexibility, more durability and security features. Business laptops use stronger materials and lighter cases, more mobility features like lightweights and wireless options. There are plenty of hardware features and software to choose from to configure to your business requirements.
Whether you are looking for business web hosting for a corporate site or cheap web hosting for a personal site, there are numerous web hosting provider that will help you to accomplish for the same. These web hosting services are an Internet based service offering online arrangements to store data, descriptions through Web.

If you are not really serious about making money online, then this would be the right time to hit back button without wasting a single moment here on this article. If you are serious, then we would be privileged to share some great online money making secrets with you. Let’s get into the issue and explore the answers to some of the widely asked questions.
What is your online identity?
You might have seen at least one stranger asking a traffic police about someone’s address in your life. If such identity doesn’t exit then how would you expect the traffic police to explain the directions! So your address is your existence in a certain locality. So if you want others inquiry about you online, then you should have an online address. Though there are several other ways to obtain an online identity, but the most secured and profitable way is; owning a website. You can specify details about yourself, your business or profession and you can add the contact details so that others can contact you.
How Can I Own a Website?
This is one of the significant steps. There are several factors involve before launching a website of your own. Domain name registration is the very step in launching your own website. This is the sole identity of your online business and your business brand. People prefer various ways before choosing a domain name. Let me add some marketing sense to this particular discussion. Though there are several other ways to access World Wide Web. Search Engines are one of the widely used resources that most of the internet users use to access and retrieve information online. Almost 80% internet users use search engines. Search engines are specifically developed to store online information (in various forms like webpage, video, image, PDF, Doc and so on) and also produce relevant information after processing the user searched keywords. There are several factors involve while synchronizing web document for a searched query. The search engine algorithm considers the URL, Meta Elements, Content and number of relevant back links to s webpage. So you should do some research before select the most popular term for your domain. Because this enables you to get your website exposed easily and quickly. The better and more relevant domain name you choose the more business you will get out of your website.
Selecting the Right Extension
There are various types of extension and this defines what type of website is yours. For example, “.com” is the extension for commercial websites; “.org” is for non-commercial organizations; “.edu” is for education institutions. There are country specific extensions too, like .in, .ie, .com.au, .us and so on. Recently there are some other new extensions are used, like, .travel and .mobi. So now you can select the appropriate extension for your website.
Once you are done with right domain name with appropriate extension, now it’s the time for selecting the right web hosting company. There are millions of web hosting companies are operating online. They promise a lot, but your negligence and ignorance can cost you heavier. So ensure everything before registering and hosting your website.
Facilitating your growing business is definitely an important issue. What was good yesterday may not work for today. Evaluating your current software, hardware and network should be done quite frequently to make certain that you are ready for the next phase of business.
Whether you are using a shared hosting account, on a VPS plan, or have your own dedicated server, hopefully your business is growing as a result of your online presence. Always stay aware of the next step in upgrading your server. Each upgrade is typically associated with an expense, so be careful to think through your upgrade plan before hand. Don’t get into a situation where you have to make an impulse decision to accommodate traffic.
One of the things you can do in the interim to ensure server optimization is to deactivate plug-ins. Each of your plug-ins takes up room and resources. Only use the plug-ins you absolutely need. If you are anticipating additional traffic at a certain time, consider deactivating plug-ins until that spike is over.
Another tactic that may help take a load off your server is to use your visitors’ browser caches. Every time someone chooses to visit your website, they use the same large resources to do so. Consider putting a header to make sure their browsers cache those components.
There are several other strategies you can utilize when looking to optimize your server. Optimizing images by decreasing their sizes will help without impacting the quality of the images much. Editing your theme or plug-ins, compressing JavaScript and CSS, and using eAccelerator all can have an impact on your server as well. If your server is hosting your company’s URL as well, you’ll want to look into a URL monitoring service to go along with the tools you select to ensure optimization.
Without directly upgrading your server, there is only so much you can do to increase its performance. The most important thing to do is to monitor your server and its growing needs. With customer retention in mind, it’s better to plan ahead and plan big, than not be able to facilitate the future.
As well known, web hosting allows companies to create their websites by providing space on a server and allowing access to the website through internet connectivity.
Whether it is shared, dedicated or reseller hosting, organizations need to choose the right kind of hosting services to suit their business. The only difference between them is focus and control. While choosing the best web hosting service, companies have to decide whether they have the technical expertise and control over the chosen service.
Cost-conscious companies looking for an inexpensive website hosting service should better opt for shared webhosting rather than go for dedicated or reseller hosting. Shared hosting allows many websites to reside on the same server making it quite inexpensive since the costs are shared between individual websites on the server. Moreover, each individual website owner has the freedom to create their own scripts. Generally, webmasters use PHP, JavaScript or HTML to make the website accessible to visitors.
Another advantage of Shared website hosting service is the control over the content created. But if a company opts for dedicated web hosting, it can control the server technology since they can host several sites on the same server as per the terms and capacity of the server space.
There are generally two types of platform for hosting a website, Linux platform and Windows platform. Although the owner can also opt for a UNIX platform, it is recommended to choose either Linux or Windows platform in hosting your website.
Linux operating system is generally preferred for demanding websites since it is considered reliable, safe and economical than Windows. Also the scripting language used depends on the type of platform. If the owner of the website uses languages such as PHP or MySQL, he will prefer a Linux platform than Windows.
Linux-based servers are reputed to have a very high uptime rate. With high uptime maintenance of 99.9%, Linux-based website hosting is the most popular and widely used web host in recent years.
A Linux based website hosting company tends to offer you features like, unlimited bandwidth, add-on domain capacity, unlimited disk storage, excellent feedback on customer support, 24/7 customer and technical support, a control panel with user-friendly features, POP3 email accounts, CGI bin access and some statistical program for analysis as well as auto responder script.
Another important factor in preferring Linux platform over Windows is the inexpensiveness. Since Linux is a free operating system, it is quite economical and can be easily converted into a Windows website without any problems. The only difference is the cost of distribution, which is borne by the web host.
When it comes to trying to start your own business online, it can be very difficult, especially if you do not have the knowledge of web hosting and do not understand the hosting business all that well. There are a few options available for you and free web hosting is one of them. In this article we will explore exactly what free web hosting is and how you can benefit from it as a business owner.
In a nutshell, free web hosting packages would offer a newbie user a crash course in the web hosting business and its countless number of features. One of the most important things that you will need to remember when you are in the market for free web hosting is to sign up with a reliable company. You do not want to risk your own personal credit card information with a company that does not know exactly what they are doing when it comes to free web hosting.
Researching any companies you are considering signing up for is probably the best idea. For instance, if you are just about to sign up with a company that seems very reliable, but then you do a quick search online and find out that information may not be true, you will be thanking the heavens that you did not sign up with that company. Knowing the company that you are signing up for, for free web hosting is very important.
Free web hosting is a great tool for the beginners who are simply looking to break into their business online. Free web hosting does come with some disadvantages though, for example, there are a lot of limitations as well as restrictiveness that could actually stunt the growth of your business. Free web hosting does not offer a lot of room for an online business to grow, but if you see that your company is starting to take off, you can purchase a web hosting account that will allow you more room to grow and fewer limitations. While a paid web hosting account is a monthly or yearly fee, if your online business is really taking off, it may be worth it.
Another disadvantage of free web hosting is that there may be a lot of pop-ups coming up on your site, the reason for this is because free web hosting companies usually display their advertisements in the form of banners and pop-up windows, so that is something to be aware of. When you decide to upgrade to a paid web hosting account, these advertisements will be fewer and far in between, but if you are okay with the advertisements, free web hosting is a great option for you.
There you have it! A complete guide to free web hosting and what you need to watch out for when you are in the market for a free web hosting company; just be sure to do you research, sign up with a company that has made a name for themselves and be aware of the pop-up windows that you may experience when you opt for free web hosting.
Web host services allow individuals and organizations to create their websites via the World Wide Web. The hosting companies connect their web servers to the internet. They are kept in a physical center called ‘data center’, which has a 24/7 secure environment complete with HVAC temperature control, virus detection software, excellent backup, as well, as disaster recovery capabilities.
Organizations that prefer web host services independently have to incur huge expenses and require the latest technology. Choosing a professional web hosting service is more viable than hosting a site independently.
Web host services generally come with two options - a free web host service and a paid web host service. While free web host services are good option, but there are chances of unnecessary advertisements popping up and distracting visitors. A paid web host service, on the other hand, is more popular with recommended features, such as, a 24 hour technical support, POP3 email accounts, CGI-Bin access and a minimum of 20MB disk space.
Web host services are classified in three main categories:
a.Shared web hosting
b.Dedicated web hosting
c.Reseller web hosting
a.Shared hosting:
Shared web hosting is used by many businesses as well as hobbyists all around the world. Shared hosting is relatively inexpensive, as several websites share the same server. In other words, websites reside on a same server with the costs shared between the individuals on the server. Most website owners create their own script using PHP JavaScript and HTML.
b.Dedicated hosting:
In dedicated hosting, an individual has his own server and does not share space with any other website. The best advantage of a dedicated hosting service is the option to host multiple websites on the same server. The individual also has this option to handle site traffic, configure software and even scale the bandwidth.
c.Reseller hosting:
Reseller hosting involves individuals selling their hosting space further. Reseller hosting is for those who want to start a business and offer shared hosting to their customers. Resellers include web consultants, such as, web designers, and web developers. Most reseller hosting companies require a dedicated server for this service.
Further, there are two platforms for hosting a website - Windows and Linux. Among these two, Linux hosting is becoming a popular choice among organizations. Since Linux is a free operating system, Linux hosting is quite economical and much more secured.
Computer security has become a major cause of worry for businesses and governments all over the world. Though internet has made e-commerce possible, helped in advertising products and services to millions of people, it has also led to the rise of criminal hacking. Due to this, a growing number of companies and governments are turning to ethical or white-hat hackers to get them out of the problem.
A certified ethical hacker tests the security of the systems, look for viruses and rectify the problems pertaining to the network security. But in order to become en efficient ethical hacker, you need to have competent skills along with the right attitude.
Programming skills
The knowledge of programming languages is a mandatory. You should learn the technique of C, C++, Python, Java, Perl and Lisp.
As a beginner, you can start by learning Python which is less complicated as compared to other languages but at the same time challenging enough. It is well-documented and well-designed. Afterwards, you can learn C, Lisp, Perl and java.
It is important to learn Perl as it is used extensively for web pages and system administration.
All these languages have different approach to programming, and by acquiring the knowledge of each one of these would make you much more efficient hacker. Each language has its own significance and at the end of the day you would benefit by learning each one of them.
UNIX
You can’t become a hacker unless you learn and understand UNIX. After all UNIX is the platform on which the Internet is built upon. Though there are other platforms, it is not possible to read the code or modify them. However with UNIX you can read how the operating system is written and modify it. Hence, learn to hack on open-source UNIX by getting a Linux or BDS-UNIX installed on your personal computer and practice on it daily for hours.
HTML
To become a hacker, you should know how the World Wide Web functions. And having knowledge of web is not just restricted to how to use the browser. You should make efforts to learn and write HTML.
Usage of English
In order to become an efficient ethical hacker, you need to have a good command over the English language, as it is the English language which dominates the Internet. All the books on hacking come in English language. Hence concentrate to improve on this part too.
Apart from all this, read lots of books on hacking. The more you read; the better. Buy books or enroll in some libraries and take them on rent. And don’t hesitate in experimenting. To become a white-hat hacker, you need to have the curiosity to learn about new things.
In fact, you can also take up hacking course. There are several reputed institutes which offer certified hacking courses with theoretical as well practical training. Getting proper training from prestigious institutes would benefit you a lot and help you in becoming a professional, certified ethical hacker.
Despite the current wave of identity theft and corporate security breaches, it's amazing how very few people treat their passwords with any level of seriousness. Most computers users, both at home and in the office, see passwords as a nuisance and therefore make them as easy to remember as possible. This can be a catastrophic mistake.
There are certain specific guidelines you need to follow to choose a safe and secure password. Use the following tips as a "how to" on making your password secure.
1. Your password must be alphanumeric. That simply means a mixture of numbers and letters such as xpf2778z. Why? When a hacker tries to break into a system, they often use what are called dictionary or brute force hacks. A dictionary hack is an application that simply uses standard words and word combinations in an attempt to guess your password. For example, many computer users use the word "password" as their actual password. A dictionary hack would crack that password in a few moments. Using alphanumeric passwords increases the number of possible password combinations by millions.
2. It should be 6 - 8 characters in length. The longer the password the harder it is for a hacking program to get around. If your password was abc then there are 6 possible password combinations. If your password was abc123 there are now over 720 password combinations possible. If your password was abc1234, there are now almost 6,000 possible combinations. Never, ever use a short password only comprised of letters.
3. Never use personal details in your password. People often use their home address, their age, husband or wives name, their social security number or their date of birth. These are incredibly easy to get access to by either a fellow employee or potential system hacker. Your password needs to be secure and hard to guess and personal details meet neither of these criteria.
4. Do not write your password down anywhere. Keeping a record of your password for somebody to find is as dangerous as keeping a copy of your ATM pin number in your wallet beside your ATM card. Create a memorable password that you will have no problem recalling. This is not as hard as it sounds and if you jot some password, ideas down you will quickly come up with some good ones. Obviously burn the piece of paper you jotted your ideas down on.
5. Do not use the same password for more than 90 days. Create several variants of the same password and recycle them every 60 - 90 days. This adds an extra layer of security to your data. By recycling your password frequently, you make your data 1000% more secure. You will notice that most large corporates force their employees to change their password every month for this exact reason.
Hopefully these tips will help you choose a password that is both safe and secure and that you will have some fun creating your new passwords too!
Adware is one of many "malwares" or malicious software programs that are unknowingly installed on your computer when you visit online sites and download freebies. When you use share files or visit sites with free downloads of wallpaper, videos, or music, some of these sites will send along adware software with your download.
These malwares are a rapidly growing threat to all computer systems. It is estimated that in the first three months of 2005 over 80% of computer users had some type of malware software program running on their computer, without their knowledge.
Although it is much less a threat to your computer and information than spyware is, what adware will do is cause pop up banners and advertisements to appear on your computer. These advertisements are displayed on your computer no matter what program you might be using. What the people who place this type of nuisance software on you computer say is that adware advertising helps them to recover costs and allows them to offer you those freebies you want.
What you want to do to stop adware from appearing on your computer is to first run an anti-adware program. Run this program on demand regularly. Along with an anti-adware software program run your regular computer virus scan on demand also.
Check the security level on your computer. You security level setting should be at least medium to help protect you from unwanted downloads.
Do not download free files from the internet, period. When downloading any software read the end-user license agreement. Some of these agreements will state that when you download their software you are also agreeing to accept a downloaded spyware that may be placed on your computer at the same time.
The internet is undoubtedly a fantastic resource for families and offers a rich vein of educational content. However, there are potential dangers - welcome to the seedy world of viruses, spam, trojans, pornography, spyware and other nasties
Here are the Top Twelve Threats No Computer User Should Ignore:
1. Viruses - A computer program that copies itself. They often disrupt your computer system or damage your data. Viruses are usually received by email attachments so be careful opening anything from a dubious source. They can affect anyone, for example, the destructive Mydoom worm affected one out of three small and mid-sized businesses.
2. Spyware - Sends information about you and your computer to somebody else. Spyware may send the addresses of sites you have visited or worse still, transmit personal information. With today's concerns about identify theft this is a real worry. For example, CoolWebSearch may hijack web searches, home page, and other Internet Explorer settings. Spyware is normally received as part of shareware freeware downloaded from the web.
3. IP Spoofing - A technique to gain unauthorized access to computers, whereby the intruder sends messages to a computer with an address indicating that the message is coming from a trusted host.
4. Trojans - An apparently legitimate computer program that is really intended to disrupt and damage computer activity by sending information, perhaps even passwords onto a third party without you knowing. As an example, recent emails entitled "Osama Bin Laden Captured" attempted to download the "Trj/Small.B." Trojan if the embedded URL was clicked. This trojan attempts to hijack the PC.
5. Spam - Unsolicited mail often promoting products of a dubious financial or sexual nature. Don't leave your email address on websites and internet bulletin boards as they are harvested by spammers.
6. Adware - puts advertisements on your screen. These take many forms including popups, popunders and advertisements that appear later, even if your browser is closed. Some are sent using the Windows Messenger service which allows a spammer to direct an advertisement straight to your computer by sequentially sending messages to IP addresses. Always irritating, they are also often of a pornographic nature.
7. Dialers - for those of us still with dial up modems, dialer programs redirect calls to a very expensive number. You won't know until you get the bill.
8. Hijackers - Hijackers take control of your web browser and may reset your home page, search bar and search pages. They can redirect you to undesirable sites or stop you going to particular sites.
9. Hackers - With so much personal data available online to anyone with a password you must be sure your password is secure. If you are using your mother's maiden name, your cat's name or your birthday then your password is at risk. Here are two tips for making a secure password. Method One - pick two random unrelated three letter words and two digits. Mix them up and what do you have? A secure password such as "red19cat" or "hotpin73". Method Two - pick a short sequence of words such as Now Is The Winter Of Our Discontent Made Glorious' and you have a password of "nitwoodmg". You could even change the I's and O's to digits.
10. Phishing - Emails purporting to come from reliable sources such as Paypal, Ebay or your bank. Often wanting you to verify your account details, they can look very realistic but are generally scams to harvest usernames and passwords. Always open a new browser winder and type the address there, rather than clicking on the link provided.
11. Hoaxes - Chain letters, scams, false alarms. At best they take up time and bandwidth but at worst vulnerable can be victims of fraud. Pass it on!
12. Stranger-danger - For those of us with children - do you know what they actually do when they are online? Are they working on homework tasks, downloading illegal music or pornography? Or are they chatting to strangers in chat rooms? You should consider blocking access to undesirable sites and logging their activity with a surveillance tool. Oh, and don't forget that where children are concerned, computers should always be kept in a family room and never in their bedroom.
Three Step Action Plan
There are three essential steps that should be taken to ensure your PC is kept threat-free.
Firstly, be sensible when opening attachments or following email instructions from apparently reputable sites.
Secondly, make sure you are using the latest service pack of Windows as Microsoft is continually closing loopholes to tighten up security.
Finally, there's a range of low cost tools such as firewalls, antivirus, spam blockers and spyware killers available. Like everything else they vary in quality and you tend to get what you pay for so always do your research first and perhaps try a free trial before getting your credit card out.
There's a quick reference list to dozens of top sites promoting different aspects of safe surfing packed with useful information and there's also a great set of top tips for safe surfing.
SSL stands for Secure Sockets Layer and it is a protocol that is developed by Netscape in order to transfer confidential documents and official data via internet. It helps in transferring the data on secure server by setting up a connection between the client and server. It is a digital certificate for your website that verifies its authentication and encrypts the information data sent using SSL (Secure Sockets Layer) technology. This encrypted data is transferred to the server in a non-readable format and is deciphered later by an appropriate decryption key.
SSL certificate acts as an e-passport that acknowledges an online identity of your website verifying its data transfer while conducting business online. When you transfer some confidential data or file on internet to a web server, your web browser gets an access to the digital certificate of the server and forms a secure connection.
The SSL certificate contains the general information including the name of the certificate holder, certificate serial number, expiration date, copy of public key of certificate holder, and digital signature of the authority issuing certificate.
SSL certification has been a boon for business organizations in ensuring the protection and privacy of personal and sensitive data. This has been necessary with the rise in outsourcing industry. Most of the nations that have expensive work labor problem get its work outsourced from countries where labor charges are cheap which saves a lot of money. Almost every business activity whether it is related to the data transfer or official discussion is conducted via Internet so SSL certification helps by allowing the secure platform for transferring the data confidently in an encrypted form which only client can decrypt with the use of key.
SSL certificate has entirely changed the working strategies of government institutions as well in many ways. E-governance has become the latest term for the government transactions taking place online. Government has upgraded its working efficiency with the introduction of high technology and e-transactions of data, documents and files in order to achieve higher performance goals. SSL has been instrumental in secured transfer of information regarding government policies, control and coordination of the various government offices and tax filing and vote or polling via effective communication system.
SSL has been recognized as an influential universal authentication program that is delivering the protection to the confidential data of worldwide government and private institutions, and has been delivering the remote networking on the most secured platform in the recent times.
The most of peoples make blunder when the topic of a computer virus arises is to refer to a worm or Trojan horse as a virus. While the words Trojan, worm and virus are often used interchangeably, they are not the same. Viruses, worms and Trojan Horses are all malicious programs that can cause damage to your computer, but there are differences among the three, and knowing those differences can help you to better protect your computer from their often damaging effects.
Computer virus
(1) Attaches itself to a program or file so it can spread from one computer to another, leaving infections as it travels. Much like human viruses
(2) Computer viruses can range in severity: Some viruses cause only mildly annoying effects while others can damage your hardware, software or files.
(3) Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it cannot infect your computer unless you run or open the malicious program. It is important to note that a virus cannot be spread without a human action, (such as running an infected program) to keep it going.
(4) People continue the spread of a computer virus, mostly unknowingly, by sharing infecting files or sending e-mails with viruses as attachments in the e-mail.
Worm
(1) A worm is similar to a virus by its design, and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any help from a person. A worm takes advantage of file or information transport features on your system, which allows it to travel unaided.
(2) The biggest danger with a worm is its capability to replicate itself on your system, so rather than your computer sending out a single worm, it could send out hundreds or thousands of copies of itself, creating a huge devastating effect. One example would be for a worm to send a copy of itself to everyone listed in your e-mail address book. Then, the worm replicates and sends itself out to everyone listed in each of the receiver's address book, and the manifest continues on down the line.
(3) Due to the copying nature of a worm and its capability to travel across networks the end result in most cases is that the worm consumes too much system memory (or network bandwidth), causing Web servers, network servers and individual computers to stop responding. In more recent worm attacks such as the much-talked-about Blaster Worm the worm has been designed to tunnel into your system and allow malicious users to control your computer remotely.
Trojan Horse
(1) Trojan Horse is full of as much trickery as the mythological Trojan Horse it was named after. The Trojan Horse, at first glance will appear to be useful software but will actually do damage once installed or run on your computer.
(2) Those on the receiving end of a Trojan Horse are usually tricked into opening them because they appear to be receiving legitimate software or files from a legitimate source. When a Trojan is activated on your computer, the results can vary. Some Trojans are designed to be more annoying than malicious (like changing your desktop, adding silly active desktop icons) or they can cause serious damage by deleting files and destroying information on your system.
(3) Trojans are also known to create a backdoor on your computer that gives malicious users access to your system, possibly allowing confidential or personal information to be compromised. Unlike viruses and worms, Trojans do not reproduce by infecting other files nor do they self-replicate.
Spyware-Adware
(1) Spyware and Adware collect information about you without appropriate notice and consent.
(2) Spyware can get installed on your computer in a number of ways. One way is via a virus. Another way is for it to be secretly downloaded and installed with other software you've chosen to install. You and I both know how easy it is to skip reading all the documentation on a free program and just click "OK." That's often how they get you.
If you've purchased a computer, or are just learning about using email and the internet, you may be faced with the problem of abnormal function of PC or system hanging problem very soon.
Somewhere down the line, there will be problems with your computer (adware, spyware, viruses, good software gone bad, etc,). Obviously, you should use protection software to prevent as much as possible. Internet is one the major source of computer virus. Usually they enter your program through an email, or while you are browsing a website.
When these programs run, usually without you knowing, they can cause all types of problems with your computer. Some viruses can be mildly annoying, slowing down your computer as they use your computer's resources for another purpose. Others can be very dangerous, collecting your personal information and sending it to another party, or damaging your hard-drive.
Once you realize that you need anti-virus software installed and running on your computer, you'll have to choose which one to purchase and install. This can be a complicated process, but here are some tips to make it a bit easier.
First, check your computer to see if it came with anti-virus software. Many new computers are shipped with anti-virus programs already to go on them, you just need to turn them on. Check your instruction manual to see if this is the case with your computer.
Check with the vendor. If you purchased your computer from a local retailer, check with them to see what anti-virus program they recommend.
I think that the best way to cure virus/worm problems is to prevent them from happening, and the best way to prevent them from hapenning is through education and awareness. Being a geek, understanding viruses seems to come naturally to me, so I figured I would share information about them with others.
If you are new to computers, please take some time and seek out professional assistance -- the rest of the Internet will thank you for it.
Here's some general tips for staying safe online:
Download and install the Firefox web browser and use it exclusively instead of Internet Explorer. IE is chock full of security holes, and new ones are being found all the time. Using IE is a big liability these days.
Do not open any file attachments from strangers. There are a number of worms which spread themselves this way. The same goes for Instant Messages from strangers.
Do not click on links in emails from strangers. There are a number of worms which spread themselves this way. The same goes for Instant Messages from strangers.
Install anti-virus software on your computer, run it regularly, and keep it updated. You can find some products listed here.
Install anti-spyware software on your computer, run it regularly, and keep it updated. You can find some anti-spyware products listed here.
Back up your data regularly. Besides viruses, there are many other things that can that cause loss of your data, such as hardware problems, software bugs, and theft of physical computer equipment. If you are looking for a primer on backup strategies and technology, I have a seperate article on the subject, available here.
This is not a complete guide to staying safe online. But, if you follow the steps outlined above, you'll make it much harder to get any sort of infection, and you'll be doing your civic duty to help keep the Internet free of viruses, worms, and spyware.
